HEATlNG-STOVE.

SPECIFICATION forming part of Letters Patent No. 395,32*?, dated January l, 1889.

Application tiled April 3, 1888. Serial No. 269,486. (No model.)

To @ZZ whom t may concern:

Be it known that we, HERBERT lIorKiNs and JOSEPH R. PERRY, citizens of the United States ot' America, residing at Hikes-Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Heating-Sto ves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in heating-stoves, having for its object the provision of simple and highly' efficient nleans :for heating water contained in a central vertical cylinder and to permit of the withdrawal of such water from below, or the emptying thereof into a tub or other receptacle located in the room above, and for producii'lg a hot-air current to warm the upper chambers.

The invention therefore comprises the dew tail Construction, combination, and arrangement of parts, sullstantially as hereinafter fully set fertili, and particularly pointed out in the claims.

In the accompanying drawings, liigure l is a vertical sectional view showing our invention. Fig. 2 is a horizontal sectional view thereot'on the line .fr a', Fig. l.. Fig. Iz) is a detail horizontal sectional view.

Referring to the drawings, A indicates a stove, provided in its lower central cylindrical portion with a ring or base, a, which forms a collar on its upper surface and is solid on its lower-,and which is supported by pipes or tubes a,extending through the casing of the stove, and provided at their outer ends with snitable slides for the admission or regulation of cold air passingthrongh them and into the central portion of the ring a, to be warmed within the hot-air line E. Upon these pipes or tubes d rests a grate, ll, an extended portion of which projects through a slot or aperture in the front of the stove to permit; of the lateral shaking thereof. This grate fits snugly around an i'ipwardly-projecting flan of the rin a, as shown, the ring a supportin and holding the grate in a central position.

C is a preferably inverted conical tube secured at its lower end by resting in the ring portion ot' the base a, and into its upper widened end is extended the lower end of a pipe or cylinder, l), which passes through the up per part of the stove, and may pass on, up through the ceiling, as shown at I), the saine being secured in an aperture thereof by suitable means for conveying the heated air. The cylinder l) may be extended to the bottom as a substitute Yfor the conical tube if desired, instead of making in two parts.

E is a hot-water or steam boiler, of less diameter than the cylinder or pipe D, wherein it is inserted, so as to form a tlue or passageway, e, between their opposite faces. The lower end of this hot-water or steam boilerE lits snugly against the salient points of a lower corrugated surface of the conical tube C, as shown at (1', llig. Iv. 'lhe purpose of this arrangement is to permit entrance of air between the conical tube C and the outer surface of boiler E. Into the ripper end of this boiler opens a water-suliply pipe, F, for supplying cold water to the boiler, regulated by valves, as is common, said water being supplied under pressure.

G is a hot-water pipe extending down into the boiler E, and its upper end is passed beyond the upper end of the cylinder or pipe D,"

and is bent or curved so as to permit of the discharge therefrom ot' hot water into atub or other receptacle by means of a faucet or other suitable discharge.

It is obvious that the heat is greatest around the lower part of the boilerlocated within the tire-pot, and that consequently the cold lwater forced down through pipe li will be almost immediately heated. As the source of supply of Awater is located above the upper end of pipe G, the water can be readily drawn from said pipe.

To the lower closed end of the boiler E secured one end of a second hot-water pipe, g, which extends out through the side of the stove, and is provided with a suitable faucet or cock, g', to permit ol" the withdrawal of hot water at this point.

It will be seen that the flue or passage-way e extends throughout the length of the boiler E, and that by reason thereof the hot air will pass up through said fine or passage-way and IOO entirely surround the boiler, thereby readily heating the water contained therein, and will escape into the chamber above.

The stove A is provided with a door, ll, and an inner lid, (not shown,) through both of which coal or other fuel is passed to the tire in the fire-pot, which fire surroumls the pipe or cylinder C.

By means of our invention water passed into the boiler is readily heated, and can be withdrawn therefrom by means oi' a suitable valve into the upper room through the hotwater pipe G, and can also 'bc readily withdrawn through the pipe g at the lower end oi' the boiler to be used for domestic purposes.

The pipe or cylinder D near its lower end is inclosed by a casing, l, supported from the top of the stove by lugs and nutted bolts or other suitable means. The object of this casing` is to divide the draft from the iireinto the stove-pipe, thereby extending the draft and heat along` the pipe or cylinder D the greatest possible extent, and, thus dividing the coal-feeder from the said pipe or cylinder, the draft will be made to pass over the top of coals in the feeder and carry ofi' the sulphur immediately as it bccomcsheated, preventing sudden explosions oi' gas.

Our invention is alike applicable i'or steamheating,l purposes by taking' or conveying the steam through a pipe connected with the boiler and coiuluctint` said steam into a suitable radiator, (not showin) the same being placed at any desired point.

' lVe claim as our inventionl. As an improvement in stoves of the class herein described, the centrally-disposed pipe. or cylinder, the ring` or base into which the lower end ol' said cylinder is secured, and the boiler located in said pipe or cylinder and supported thereby at its lower end, a tiue or passage-way being' formed thereinb etween, substantially as shown and described.

2. As an improvement in stoves of the class herein described, the stove having` the ring or base, the conical tube secured at its lower end in said ring or base, the pipe or cylinder attached to the upper end of said conical tube, and the boiler inserted `in said pipe or cylinder, whereby a hot-air line or passageway is formed, substantially as shown and described.

As an improvement in stoves of the class herein described, the stove having the central pipe or cylinder, the boiler secured therein and supported thereby at its lower end, the water-s npply pipe, and the hot-water or steamexhaust pipes connected to said boiler, substantially as shown and described.

4. The combination, with a stove having the ring` or base, ot' the pipes or tubes supporting said ring` or base and opening thereinto, the pipe or cylinder supported by said ring' or base, and the boiler disposed in said pipe or cylinder and resting,` vagainst the lower conical tube thereof, substantially as shown and described.

5. The herein-described improvement in stoves, comprising the ring or base, the pipes opening into said ring` or base and supportini,r the saine, the central pipe or cylinder, the boiler inserted int-o said pipe or cylinder, the hot-water pipe extending' in to said boiler, and the hot-water pipe connected to said boiler at its lower end and having a cock or faucet, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
